STATIC AND DYNAMIC ANALYSIS ON THE GRAVITY DAM ANTI-SLIDING STABILITY UNDER UNITED FORM BETWEEN DAM AND PLANT

摘要：

In this paper, the deep and shallow anti-sliding stability of gravity dam under united form between dam and plant is analyzed in Jinanqiao hydropower plant sect, through the method of limit equilibrium and strength accumulation coefficient method. Based on the geological data, from which the left plane in double-inclined slide mode can be ascertained, a function is educed between structure coefficient and obliquity of the right plane in the double-inclined slide mode; then the worst anti-sliding structure coefficient can be known. At the same time, strength accumulation coefficient method is adopted for safety checking. The results of the both methods show, for the Jinanqiao hydropower riverbed dam sect, the deep and shallow anti-sliding stability can be ensured, and the united form can well improve anti-sliding stability of the dam bedrock.
